and it is the primary object of the invention to provide a portabledevice of this character which may be readily andeesily set up toaccomplish the lifting result.

A further object of the invention is to provide a ,deviee of thischaracter con- 'structed so that the weight of the article being lifted,will cause the lift proper to be held in a rigid position'during thelifting operation.

A still further object of the invention is to provide a lift which maybe operated and controlled by a single person, and to enable the personto position carpet or other floor coverings under the article beinglifted.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing Figure 1 illustrates a side elevational view ofthe lift.

Fig. 2 illustrates a plan View of the same, and

Fig. 3 illustrates a front elevational view showing the lift as appliedto a range.

Referring to the drawing in detail, the lift comprises an upper sectionincluding spaced arms 5 which are formed preferably of relatively rigidmaterial having the converging arms 6 formed adjacent one end thereof,which arms terminate in offset portions bolted together by means of thebolts 8 and 10.

The bolt 10 which connects the arm 6 also forms a pivot pin for the bellcrank lever 11, which has its upper end connected with the operatinglever 9 by means of the connecting armslQ, that have pivotal connectionwith the lever 9 through the medium 6, the extreme ends thereof being.

of the bolt 13, so that movement of the operating lever 9 produces arelative movement of the arms 12 and the bell crank lever 11.

One arm of the bell crank lever 11 is apertured as at 1% to receive oneof the links of the chain 15 which has connection with the liftingchains 16 arranged to cross each other so that the free ends thereof, bemoved to positions in spaced relation with each other, and be connectedwith an article, at vzu'ious points thereof to permit the article beinglifted to be properly balanced, facilitating the lifting operation.

Disposed on: the free ends of the lifting chains 16, are t 1e hookmembers 17 which are of structuresto permit the same to be easilypositioned over the article to be lifted in a manner to prevent slippingof the article with relation to the hook members.

A. yoke indicated at 21 has connection with the arm 6, by means of thebolt 8, the bolt 8 which also has connection with the yoke provides apivot pin for the upper end of the supporting leg 18 which has its upperend curved as at 19 and positioned between the extreme ends of the arms6, adjacent the offset portion 7 thereof, and as shown the opposite endof this supporting leg 18, is pointed as at 20 so that the weight of thearticle being lifted will force the pointed extremity 20 into the floorsurface on which the support is positioned, and since this supportingleg 18 is positioned at an angle with relation to the horizontalposition of the arms 5, it will be seen that the outer endsof the arms5, are forced into close engagement with the wall with which the sameare associated, during the lifting operation.

In the drawing, the device forming the subject matter of the presentinvention is shown as employed for lifting a range, to enable a floorcovering to be positioned thereunder, and in this showing the arms 5have their free ends engaging the Walls adjacent to the stove, the lever9 is in a position to be moved downwardly with the result that the armof the bell crank lever 11, which carries the aperture l l, movesupwardly, carrying therewith the lifting chains 16 which in turn haveconnection with the upper flange of the range. The floor covering maynow be rolled under the stove by the person operating the lift,whereupon the operating lever 9 is now moved to the position asindicated'by Fig. 1 of the drawing, and the range again moves downwardlywhere the same rests on the floor covering.

It might be further stated that as the lever 9 is moved downwardly, toaccomplish the lifting operation, the arms are forced into engagementwith the wall adjacent to the stove, under the weight of the stove beinglifted, to prevent movement of the arms 5.

Having thus described the invention, What I claim as new is 1. In alift, a pair of spaced arms, said arms having portions thereofconverging and secured to ether an o cratin lever ivotally supportedbetween the arms, a bell crank lever pivotally supported between thearms, means having connection with the bell crank lever for securing thedevice to an article to be lifted, a supporting leg, and means forconnecting the bell crank lever and operating lever to cause the bellcrank necting the bell crank lever and operating lever, lifting chainshaving connection with the bell crank lever, said lifting chains adaptedto move vertically when the operating lever is moved in one direction,and a supporting leg having pivotal connection with the arm.

3. In a lift, a pair of spaced arms, an oprating lever having pivotalconnection between the arms, a bell crank lever pivotally connected withthe arms, means for connect- 3 ing the bell crank lever and operatinglever, whereby movement of the operating lever produces a relativemovement of the bell crank lever, lifting chains having connection withthe bell crank lever to move therewith, and a supporting leg havingconnection with the arms, the supporting leg having apointed extremityadapted to pierce the floor surface on which the lift is positioned.

In testimony that I claim the foregoing as my own, I'have hereto affixedmy signature in the presence of two witnesses.
